Love the fork, it's super cool you added those error checking and status code features :)

re your points:1. In the starter repl, I've used KEY itself - I hadn't in the demo instance, just changed that.

Yes, this is something I've seen other people struggle with too. It'd be dope if forks would also clone the env, except it'd be unpopulated - so the key names and comments will remain, just without the actual values.@amasad: Feature suggestion :)

The shortener should work fine even without the base URL, since it uses relative links.
